The great shame about most art games is that they lack challenge.
You've created a competent and stylish platform game but the level design really lets it down.
I know, i get it, that you weren't trying to make a really tough game, but the experience and the message of the game are marred entirely by the straightforward nature of the gameplay. I wouldn't play it again, or recommend it particularly, because of this oversight.
All in all, it's really pretty, and you're obviously capable. Please come back with something really frustrating. Also, great music, really great, but please include a mute button.
